“…However, vascular access procedures continued to make up a significant proportion of IR procedure work. 23,24 Prior to the pandemic, we aimed to avoid temporary lines or THLs, largely due to increased complication risk associated with lines compared to AVF/AVG, and to preserve venous real estate in our patients. 25,26 The long-term effects of the change in our practice and increased THL use due to COVID-19 remain to be seen.…”

The management of dialysis access thrombosis during the COVID-19 pandemic

Background: Maintaining patent access is essential for haemodialysis dependent end stage renal failure patients. The COVID-19 pandemic has significantly affected surgical and interventional radiology services worldwide. We aimed to review the impact COVID-19 has caused to the management of acute dialysis access thrombosis. Methods: We conducted a single centre retrospective review of outcomes of patients with arteriovenous fistula and arteriovenous graft thrombosis between March and May 2020, which coincided with the first peak of the COVID-19 pandemic in London, and a similar period in the previous year, March–May 2019. Outcomes in both cohorts of patients were compared, including attempts at salvage, salvage success, 1-month patency rates after salvage and subsequent surgery on the same access. We also analysed the use of tunnelled haemodialysis lines (THL), either due to failed salvage attempts or when salvage was not attempted. Results: There was a similar incidence of access thrombosis in both periods (26 cases in 2019, 38 in 2020). There were 601 patients dialysing via an arteriovenous fistula or graft in 2019, and 568 patients in 2020. Access salvage, when attempted, had similar success rates and 1-month patency (salvage success 74% vs 80%, p = 0.39; 1-month patency 55% vs 62%, p = 0.69). The proportion of patients where access salvage was not attempted and a THL inserted was significantly higher in 2020 compared to 2019 (32% vs 4%, p = 0.007). There were more patients who subsequently had surgery to salvage or revise the same access in 2019 compared to 2020 (62% vs 13%, p < 0.001). Conclusions: During the peak of the COVID-19 pandemic, there were fewer attempts at access salvage. This was a conscious decision due to increased pressure on the healthcare system, access to emergency interventional radiology or operative theatres and the perceived risk/benefit ratio of access salvage. The long-term effects of this change in practice remain unknown.

“…Elective interventional radiology procedures saw a broad reduction in numbers compared to the pre-pandemic era. 7 , 8 These changes resonated with various societal guidelines published by both interventional radiology and surgical institutions. 9 , 10 However, given the heterogeneity of the disease characteristics of HCC 11 , 12 compounded by the dynamic state of the COVID-19 pandemic across nations, institutions struggle to conclusively provide recommendations for the treatment of HCC.…”
